The DCIF houses a Bruker EMX spectrometer, an ER 4199HS cavity and a Gunn diode microwave source producing X-band (8-10 GHz) radiation. The instrument also has a cryo-cooled cavity for low temperature experiments down to about 5 K. The instrument is controlled with a Windows-based computer running the Bruker Win-EPR Acquisition software. The Bruker Win-EPR and SimFonia software packages are also available for off-line data processing.
